Title
Earth Resources Technology Satellite (ERTS)
Full Description
The Earth Resources Technology Satellite (ERTS) mock-up in a
space chamber test at General Electric's Space Division. The
ERTS program represented a concentrated effort to observe and
monitor the limited resources of the Earth, in order to best conserve
and utilize the resources in support of a burgeoning world
population. The first ERTS was launched in 1972 and was later
named Land Remote-Sensing Satellite (Landsat), to better represent
the civil satellite program's prime emphasis on remote sensing of
land resources. Multiple sensors survey and relay back masses of
data in various ways from the Landsat. NASA has built 7 Land
Remote Sensing Satellites, which have helped agricultural experts
pick up underutilized land areas and new prospects for land use
through irrigation. It has also assisted in pinpointing the spread of
crop disease and in charting new uses of the sea for
oceanographers.
